And then that old tech is still around for a long, long time.... Piston aeroplanes are still flying today. New ones, in small 2, 4 and 6 seat capacity are still being built[0]. Some older piston aeroplanes, perhaps in the region of 40-60 years old, are being overhauled and modernised for commercial flight training use.[1] Some larger 8-12 seat piston aeroplanes are still in use carrying commercial passengers and cargo[3] and also have various modernisation upgrade options available.[4] Of course there are modern turboprop aeroplanes which can do the same jobs better - for some definition - but the issue is economics. The capital investment in a turboprop outweighs the cost of maintenance and Avgas in an older piston engine design. (This is changing due to the fact of Avgas becoming very scarce in many regions of the world.) The point being, I wouldn't expect the PC, with keyboard and mouse paradigm, to disappear in the near future. I'd still expect many white collar workers to be sitting at their desk, typing on a something resembling a keyboard, in 50 years time.
